The violence that struck a ballfield in Alexandria, Va., on Wednesday abruptly plunged what had been a routine start to the day in the Del Ray neighborhood into chaos. Residents were focused on morning workouts and getting coffee; a congressional contingent had driven over for an early baseball practice. But then the shooting started, and they all scrambled for cover.

House Majority Whip Steve Scalise of Louisiana has undergone surgery and will need further operations, after being shot by a man who opened fire with a rifle on an early morning baseball practice for Republican members of Congress in Alexandria, Va. Scalise was the most seriously injured of four victims of the shootings.
